Answer:
B, C, Dand E are all correct
Explanation:
Why B is correct- The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm (the contents of the cell) from its surrounding environment. It is selectively permeable, which means that it only lets certain molecules enter and exit.
Plants, animals, and bacteria have a cell membrane. Why d is correcect
Why C is correct- The cell membrane is not a solid structure. It is made of millions of smaller molecules that create a flexible and porous container. Proteins and phospholipids make up most of the membrane structure.
Why E is correct- The plasma membrane is primarily composed of phospholipids arranged in a bilayer, with the hydrophobic tails on the interior of the membrane, and the hydrophilic heads pointing outwards
Why A Is Not correct- It is very fragile and its role is to hold the cell together and to help control what substances can get in and out. It is partially permeable, allowing only some substances to pass through it. The membrane has a complex structure consisting of a phospholipid bi-layer and different types of proteins.
Answer:
Ecological niches allow species to exist in their environment. Under the right conditions, the species will thrive and play a unique role. Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.
If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.
Explanation:
Answer:True
Explanation:Changes made because of artificial selection <u><em>CAN</em></u> result in seemingly beneficial traits that prove to be detrimental over time
While some might be familiar, nature provides us with about nine million distinct species (although only 1.5 million have been identified). Beauty is not limited to the hundreds of animals that most people can readily identify. Some fun facts will be provided about each of the ten animals.
Trypanosoma brucei obtain food by using its host, the Tsetse fly. It's a parasite that lives inside the fly and as the fly searches for food which is blood from animals or humans, the parasitic organism transfers. Inside another host, the organism feeds, grows and multiplies.
Hope this helped. :)
